card0/error file as referred to in dmesg

With CONFIG_X86_64_SMP, X either

...works
...does not start after `startx` and freezes with a black screen, underline
cursor in the top left and has to be killed by cutting the power
...does not start after `startx` and freezes with a black screen, underline
cursor in the top left and has to be killed by SysReq or cutting the power
...works at first and then freezes
...works at first and then starts showing artefacts (large black areas) in
anything even slightly rendering expensive (webpages in firefox)
...shows artefacts right from the beginning

at complete random. Without SMP support, no problems are encountered. Attached
you find dmeg and card0/error after X worked at first but then suddenly started
showing errors (and eventually freeze completely).
